Is this an "Anything goes" kinda deal? I can give you an approach, but it'* not very descript....

If you are looking for parts.. S1 parts are probably going to end up being Austraiian. They have performance parts.

Now..if you want to build a monster and might consider an S2.. talk to Intense and ZZP.
you make it sound like you need a series 2 to have a monster. but you are right on where to go for parts.

Basically it is this. You have to find a way to get it to the ground.... and hold it. Secondly, you have to have an engine physically sturdy enough. I don't know how strong the block is, and I have no idea about the internals either. You will have to research that. Full on machine work would be a plus to help it last, and give you a few more horsepower. Other than that, you just need to find a way to stuff air into the engine as efficiently as possible, you also have to figure out how to get it out of the engine, and how to fuel that monster. A big turbo and lots of nitrous, a good cam and killer heads seems like the simplest way, but you're talking big money for something that may or may not last long, as well as possibly lose it'* streetability.

You're speed is not always, but most commonly directly proportional to the size of your wallet.


*edit*
Possibly you would require structural bracing on the chassis of the car. You would want a new braking system. It'* fun getting up to speed, but you have to slow down too. Roll cage is required at those times/speeds. All of the needed safety equipment basically. Stuff required by rules and regulations at drag strips. Weight reduction would be a plus. And again, a way to get it to the ground. The drivetrain, as well as the tires, and getting them to hold(weight transfer on launch hurts you). Probably a lot of things I'm leaving out. This is a simplified version that in my mind *SHOULD* work, but would be no sure thing.

The newest S1 blocks are 12ish years old, have been driven atleast 50k miles. How they hold up, or are setup for big power is uknown, but it'* my understanding that the waterpump begins, or is cavitating at 5-6k RPM in most 3800'*, the oil system will need to redone most likely.

Heads, manifolds, super/turbocharger will all need to be done custom, i'm sure a standalone computer will be necessary. Transmission will need to be built a lot, custom suspension, fenderwells setup for slicks, maybe some new tubular control arms, hubs, etc.

it'll take damn near 900-1000hp through the crank to turn a 90'* H body into a 9 second door slammer. It wont be streetable, at all.

Aussie L27 blocks hold plenty of power. Look up the holden V6'*.

Fenderwells modified for slicks?



A standalone engine management system would be best, but that'* going to be tricky with an Auto trans.

Yeah, they'd have to be bigger then anything that could fit on a std bonne rim, that'* for sure.

I disagree completely. There'* plenty of room for my slicks to grow.

tall deck blocks rule...longer rods help top end breathing, the rear bulkhead is substantially stronger and stiffer than the SII rear bulkhead fwiw

that said...i wish i had enough $ to build my dream engine too...


and Will, i already looked into it...i do believe you could convert an OBDI SI 3800 to run with a OBDII 98-02 SII harness and PCM, the only issue i found is the extra knock sensor...and from what i saw it would just be mounted at a 90* angle from the SII location...you could keep the hydrostatic trans or go with the electronic transaxles. your thoughts?

well, guess I'm going to find out what it'll take, I know this is a bonneville site, but when I DO get the series 1 motor into the 9'*, it will be in a beretta body.
